Sir William Coventry, (born c. 1628—died June 23, 1686, near Tunbridge Wells, Kent, Eng.) English statesman, one of the ablest and most respected figures of Charles II’s reign.

Coventry entered Queen’s College, Oxford, in 1642 but soon left to join the Royalist army and later followed the court into exile. He returned to England in 1652 but, by refraining from Royalist activities, survived unmolested to assist in the Restoration of Charles II. James, Duke of York, made him his secretary in 1660, and he was elected member of Parliament in 1661. He became commissioner of the navy in 1662 and a member of the treasury commission in 1667. In this post and as an outstanding speaker in the House of Commons, he led a determined drive for administrative efficiency. Regarding the Earl of Clarendon as an obstacle to this, he resigned from the Duke of York’s service in September 1667, but he did not join in Clarendon’s impeachment. Economies in expenditure became his principal concern during 1668, and the king’s resentment at the restraints that these imposed made it easier for the Duke of Buckingham to secure Coventry’s disgrace in 1669. Coventry was released after a short confinement in the Tower of London, utterly disillusioned with public service and determined never to take office again. Although he remained in Parliament until 1679, he retired thereafter to his country house.
